' RAZOR BLADE.

Application filed January 5, 1922. Serial No. 527,130.

To aZZ whom it may concern:

Be it known that I, DENNIS E. HICKEY,

' a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented new and useful Improvements inRazor Blades, of which the following 1s a speolfication.

My invention relates to detachable razor blades, and more particularlyto blades of polygonal design having a plurality of cutting sides.

An important object of the invention is to provide a blade of the abovementioned character, the formation of which is such that one of thecutting sides may be used without danger of the shave'r cutting his faceon the nether corners of the adjacent cutting sides.

A further object of the invention is to provide a blade of the abovementioned.

character, the various cutting sides of which may be flexed withoutbringing their ad j acent' edges into contact with each other.

A still further object of the invention is to provide a blade which maybe readily picked up when lying on aflat surface without cutting thefingers.

' -These and other objects are attained by means of a novelfcombinationand arrangement of parts to be'hereinafter described and claimed, and inorder that the same may be better understood, reference is hard to theaccompanying drawing forming a part of this specification and inwhich'the preferred embodiment of the invention is disclosed. a

In the drawings,

.Figure 1 is an elevation showing one face of the blade;

Fig. 2 is a similar view showing the other face, and

Fig. 3 is an edge view.

Referring specifically to the drawing, wherein like characters ofreference desig nate like parts throughout the several views, 5 denotesa blade having outwardly directed wings 6, the-outer edges 7 of whichare sharpened to form cutting surfaces. The blade 5 is made of thinflexible steel so that it may be readilyflexed when fitted into asuitable holder or guard. The wings 6 are formed by cutting a diagonalslot 8 inward from each corner of the blade and flaring the sameoutwardly at the ulterior end thereof as shown at 9, thus giving thewings 6 a-bell-shaped configuration, w1th the side edges thereofapproaching the cutting edges at right angles, said side edges androunded corners being-blunt. It will thus be seen that each of the wings6 may be flexed 25 degrees or more independently of each other withouttheir adjacent edges contacting or coming into such close proximity asto hinder the shaver. The rounded corners and side edges of the wingsbeing blunt, it is unnecessary that the blade holder used be providedwith a guard for each wing to prevent accidental cutting of the face bywings not in use, and a holder with but a single guard may be employed.

Each side of the blade 5 has a number of protuberances 10, the samebeing pref erably located, one on either side of each wing 6 andintermediate the interior ends of the adjacent slots 9. By placing theseprotuberances 10 in a position well back from the cutting edges 7 of thewings the flexing of the wings G is not interfered with and the rearportion of each wing is slightly stiffened and strengthened to preventliability of breakage. These protuberances 10 also serve to elevate theblade from the marble slab or other supporting surface on which it mayhave been laid and thus permit the same to be readily picked up, theblunt rounded corners 9 and edges of the wings 6 adjacent the cuttingedges serving to prevent cutting of the fingers in picking up the blade.

' A centrally located and polygonally shaped aperture 11 is provided inthe blade I to receive the similarly shaped shank of the handle of therazor (not shown) to prevent any turning movement of the same relativeto the blade. I have not described or illustrated my razor blade inconnection'with a handle, clamp plate, -etc., since the razor, per se,forms no part of the present invention and any type of razor adapted toreceiyie a polygonally shaped blade may be use It will be seen that theslots 8 flare substantially .at' their outer ends so as to provide afinger receiving means. This permit ones fingers to be convenientlyengaged with the blade without the possibility of accidentally cuttingthe lingers. A second and equally important advantage in flaring theouter ends of the slots resides in the fact that the blade may bereadily cleaned. In fact, this construction renders the bladeself-cleansing to a high degree.

In other Words, lather will not collect and remain in the slots as itwould if the slots were enlarged or flared at their inner ends. It isthus seen that the double purpose served by the flaring of the slots attheir outer ends adds greatly to the utility and -my invention, it willbe understood that various changes and modifications may be made 111 thesame'withm the spirit and scope of what 18 claimed hereinafter.

I claim:

A razor blade comprlsing an approxi- ":rnately triangular body havingthe corners thereof formed with slots flared substantially at theirouter portions for the reception of ones fingers and defining aplurality of cutting members the side Walls of said slots having theirinner portions parallel and and their outer portions curvedlongitudinally and disposed at substantial right angles to the cuttingedges of said cutting members, the ends of each cutting member beinglocated beyond and a substantial distance rearwardly of the ends of theadjacent cuttingvmembers and projections placed at the centre of eachblade upon both sides of the blade for holding the body of the blade inspaced relation to a support so that grasping of the blade isfacilitated In testimony whereof I afiix my signature.

DENNIS E. HICKEY.
